Welcome to the forum and congratulations on your first cow !
The fact that you have cared for other types of livestock will pay dividends plus of course as it's a calf you will have plenty of time to learn all you need before you have to start thinking about the milking side of cowcare.
There are some useful articles on this very site Try here
I'd also advise checking out some of your neighbours or maybe a local farmer and see if you can do some part-time work for them to learn more.
You might even consider doing a course at your nearest agricultural college but while theory is all well and good there is nothing like hands-on' experience.
I wish you all the best, keep in touch and let us know how you go ok ?!
